START UP
After having correctly installed the ice maker and
completed the plumbing and electrical
connections, perform the following "Start-up"
procedure.
A.
Remove the unit front panel and locate
the cleaning switch on the control box.
B.
Set the cleaning switch in the cleaning
position. This will close the electrical circuit to the
water inlet valve and to the hot gas valve
C.
Switch ON the power line disconnect
switch. Unit will start up in defrost cycle mode.
During this cycle the components energized are:
WATER INLET SOLENOID VALVE
HOT GAS SOLENOID VALVE
The Water pump and the Fan motor are also in
operation.
D.
Let unit stay in defrost cycle for about
three/four minutes till water is coming out from
the drain hose, then move the cleaning switch to
the operation position.
NOTE. During the defrost cycle, the water
inlet solenoid valve is energized. The water
flows through the valve to the back side of
the evaporator platen and then down to fill up
the icemaker sump tank for the next freezing
cycle.
OPERATIONAL CHECKS
E.
The unit now starts its first freezing cycle
with the following components in operation:
COMPRESSOR
WATER PUMP
FAN MOTOR in air cooled version
F.
Check to see through the ice discharge
opening that the spray system is correctly seated
and that the water jets uniformely reach the
inverted molds; also make sure that the plastic
curtain is hanging freely and there is not excessive
water spilling through it.
OPERATING INSTRUCTIONS
G.
thereby, with the water sprayed on the inverted
molds that gets gradually refrigerated by the
heat exchanged with the refrigerant flowing into
the evaporator serpentine.
H.
a preset value the evaporator thermostat or cube
size control changes its contacts; the freezing
cycle ends and starts the defrost or harvest
cycle.
I.
cycle, that the incoming water flows correctly
into the sump reservoir in order to re-fill it and the
surplus overflows through the overflow drain
tube.
J.
dimension of ice cubes just released.
If not, wait for the second defrost/harvest cycle
before performing any adjustment.
K.
can be modified by turning with very little
movements (6 degree or 1 minute each time) the
knob of the cube size control evaporator
thermostat located in front of the control box until
the desired size is achieved.
If the ice cubes are shallow and cloudy, it is
possible that the ice maker runs short of water
during the end of the freezing cycle or, the quality
of the supplied water requires the use of an
appropriate water filter or conditioner.
L.
handful of ice cubes against the bulb of the
storage bin thermostat; the icemaker switch OFF
in about one-two minutes.
Take out the ice from the storage bin thermostat.
The ice maker should restart automatically in
three-four minutes.
NOTE. The bin thermostat is factory set at
1 ° C OUT and 4 ° C IN.

machine and about the cleaning and care it
requires.
